SGS3 MHL adaptor does not do MHL & USB OTG simultaneously
We’ve recently had the question asked on the Clove Blog if the Samsung Galaxy S3 and Samsung Galaxy Note 2 can do MHL (video out) and USB On The Go simultaneously.
There has been some speculation that, due to the new 11-pin connector design used on the SGS3 (and Note 2) for MHL, the MHL adaptor for the S3 would be able to offer MHL and USB OTG simultaneously. These comments appear to have come from an MHL spokesman and do not seem to have been proven to be true either way up until now.
We have now had the chance to try an Samsung Galaxy S3 official MHL adaptor and an official Samsung Galaxy S3 USB OTG cable with the international Samsung Galaxy S3 and the international Samsung Galaxy Note 2 and can confirm that the simultaneous use of MHL and USB OTG cannot be achieved in this way.
Theoretically, if the S3/Note 2 could themselves power the connection for the MHL adaptor (as has been mentioned previously), the microUSB port on the MHL adaptor would be left free and could therefore be used for USB OTG. However, the S3 (and the Note 2) are unable to power the MHL adaptor and a separate mains input from a microUSB charger is required.
That’s not to say that the functionality is not built into the devices, but as things stand they cannot power the MHL adaptor without a secondary input and therefore the simultaneous use of USB OTG is not possible. We haven’t had the official Note 2 MHL adaptors in yet, but we have found that the SGS3 MHL adaptor works with the Note 2, so for the time being the same logic can be applied as to it not being able to power the MHL adaptor on its own. Once we’ve had the official Note 2 MHL adaptors in, we’ll see if it can do MHL and USB OTG simultaneously.
The kind of setup that would be achieved by having MHL and USB OTG work simultaneously will be made possible by the Samsung Galaxy Note II Smart Dock, for which we await pricing and availability details. Seeing as the SGS3 MHL adaptor works with the Galaxy Note 2, it is possible that the Note II Smart Dock will be compatible with the SGS3. We will confirm this as soon as we have received stock.
